indicative tests using chemical reagents on the substance. The indicators allowed the team to narrow down the possibilities to find out the contents of Mr. Bean’s last meal. Indicators are chemical reagents that help identify the presence of certain macromolecules in a solution. The team specifically tested for the presence of starch, monosaccharides, protein, and lipids; there was a possibility for each of the four to have been present in Mr. Bean’s dinner. The investigators initiated the test for protein

579 Atomic force microscopy and other scanning probe microscopies Helen G Hansma and Lía Pietrasanta The highlight of the past year is the unfolding and refolding of the muscle protein titin in the atomic force microscope. A related highlight in the intersection between experiment and theory is a recent review of the effects of molecular forces on biochemical kinetics. Other advances in scanning probe microscopy include entropic brushes, molecular sandwiches and applications of atomic force microscopy

Structure Analogies a) Nucleus- The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. These two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). b) DNA- It is a molecule that stores genetic information required for the development of the body and the control of

Title: Identification of the Main Groups in Macromolecules- Carbohydrates Objective: To investigate and identify the different types of carbohydrates Background: Macromolecules are large molecules that are present in our body. There are four main types of macromolecules, namely carbohydrates, lipids, proteins, and nucleic acids. Each one of them plays specific and significant roles in our body and each one of them is extremely important. If we are lacking either one of them, our body would

Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates, lipids, and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia, 2012). Many are structural components of bone, muscle, hair, tissue, etc. Others are enzymes that speed up cellular reactions. All proteins are made up of amino acids (Johnson, 2010). The purpose of this

Chemistry of DNA The chemistry of DNA (deoxyribonucleic acid) is not as mysterious as some make it out to be. DNA is simply the hereditary material in all of living organisms; the biological instructions that make each species unique (National Human Genome Research Institute, 2012). Every part of our bodies contains tiny cells of DNA and within the nucleus of these cells is the information of hereditary. Nucleic acids are the building blocks of information storage; DNA and RNA (ribonucleic acid)

Ribosomes are multi-subunit macromolecules that contribute to the formation of many crucial proteins that maintain a balance of function in many living organisms. They primarily function by translating mRNA’s into their corresponding amino acid sequences. A protein’s correct output of amino acid order and consequently its structure are dependent strongly upon the correct formation of the ribosomal subunits in the particular organism’s ribosome. Degradation or incorrect structural formation of
